NRC proposes changes to its rules on nuclear materials
In response to Executive Order 14300, “Ordering the Reform of the Nuclear Regulatory Commission,” the NRC is proposing sweeping changes to its rules governing the use of nuclear materials that are widely used in industry, medicine, and research. The changes would amend NRC regulations for the licensing of nuclear byproduct material, some source material, and some special nuclear material.
As published in the May 18 Federal Register, the NRC is seeking public comment on this proposed rule and draft interim guidance until July 2.

Sensitivity methods based on generalized perturbation theory are very valuable tools for the reactor designer in many areas of interest. In general, the first-order formulations are routinely used, and higher order effects are neglected. In the present Note, we have developed a practical approach to take into account higher order effects in time-dependent sensitivity analysis in the nuclide field for fuel-cycle-related problems, and we give examples of its use in cases of interest.
